The phase constitution and morphology were evaluated through X-ray diffraction, microstructural analyses (scanning electron microscopy/energy-dispersive X-ray spectroscopy), and thermodynamic calculations (ThermoCalc). The as-cast alloys exhibited a TiNi matrix, β-Nb/TiNi eutectic, and Ti2Ni precipitates. Under equilibrium conditions, TiNi and a small fraction of β-Nb were expected. Increasing the Nb content resulted in a higher β-Nb volume fraction, development of different morphologies for Ti2Ni precipitates, and formation of Ti particles. The Scheil calculator and virtual composition of the liquid were used to simulate the effect of chemical segregation during solidification. We demonstrated that the metastable phases formed during solidification and the Nb content played a vital role in the solidification sequence, phase distribution, and morphology of the alloy.engUniversidade Federal de Minas GeraisUFMGBrasilENG - DEPARTAMENTO DE ENGENHARIA METALÚRGICAENGENHARIA - ESCOLA DE ENGENHARIAJournal of Materials Research and TechnologyTermodinâmicaEngenharia metalúrgicaMicrostructural characterizationShape memory alloysTiNiCu-based alloysThermodynamic simulationsRole of Nb on the phase stability and morphology of Ti–Ni–Cu–Nb alloysinfo:eu-repo/semantics/publishedVersioninfo:eu-repo/semantics/articlehttps://www.sciencedirect.com/science/article/pii/S2238785422012066?via%3DihubJéssica Dornelas SilvaGisele Fernandes Chaves MacieiraDilson Silva Dos SantosLeandro de Arruda SantosVicente Tadeu Lopes Buonoapplication/pdfinfo:eu-repo/semantics/openAccessreponame:Repositório Institucional da UFMGinstname:Universidade Federal de Minas Gerais (UFMG)instacron:UFMGLICENSELicense.txtLicense.txttext/plain; charset=utf-82042https://repositorio.ufmg.br/bitstream/1843/60734/1/License.txtfa505098d172de0bc8864fc1287ffe22MD51ORIGINALRole of Nb on the phase stability and morphology of Ti–Ni–Cu–Nb alloys.pdfRole of Nb on the phase stability and morphology of Ti–Ni–Cu–Nb alloys.pdfapplication/pdf2956480https://repositorio.ufmg.br/bitstream/1843/60734/2/Role%20of%20Nb%20on%20the%20phase%20stability%20and%20morphology%20of%20Ti%e2%80%93Ni%e2%80%93Cu%e2%80%93Nb%20alloys.pdf8b76ceba8471ba37f2fa225be0213009MD521843/607342023-11-09 18:36:03.965oai:repositorio.ufmg.br:1843/60734Repositório de PublicaçõesPUBhttps://repositorio.ufmg.br/oaiopendoar:2023-11-09T21:36:03Repositório Institucional da UFMG - Universidade Federal de Minas Gerais (UFMG)false |
